Shocker Hitch HD 20K 2 Inch Air Receiver Hitch & Drawbar with 1 Inch Hole

Description

Bumping across frozen ruts and washboard farm roads damages truck drivelines when towing heavy equipment. The Shocker Hitch HD 20K Air Receiver drawbar absorbs harsh fore-and-aft tongue bucking up to 20,000 lbs. It fits 2in class 4 receivers. The rigid drawbar tang does not accept standard trailer balls, requiring separate attachments for ball towing.

Plate steel side uprights enclose an industrial rubber air spring inside a welded chassis frame. The solid 2in square steel shank slides into class 4 truck receivers, anchored by hardened cross pins. Bare hitch weight measures 58 lbs, occupying envelope dimensions of 14in length by 8in width by 12in height. Greasable bronze pivot bushings support the drawbar tang, handling 2,000 lbs vertical tongue force without pin bore distortion.

Drawbar Dynamic Shock Isolation Benchmarks

Dynamic test rams verify a 72 percent reduction in longitudinal shock transfer between farm implements and the truck frame. Under a 1,600 lbs tongue load, the internal air spring cushions road impacts without bottoming out against frame stops. Drawbar hole wear tests show zero bore elongation after 100,000 tension cycles at 15,000 lbs draft pull. Air chamber seal tests confirm zero leakage across 1,000 continuous hours at 60 PSI. In-cab noise monitors record a 14 dB clatter reduction on washboard gravel.

Field Setup Implement Maintenance Schedule

Hooking up farm equipment requires inserting a 1-inch pin through the drawbar and securing the linchpin by hand. Do not purchase this hitch for ball-coupler trailers without buying a separate ball mount bracket.

• Inject NLGI 2 lithium grease into pivot zerks every 30 days.
• Check air spring pressure with an accurate gauge every 14 days.
• Inspect the 1-inch drawbar pin hole for wear every 6 months.
